Yann Kernin has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Tube inspection unit with eddy current probe and corresponding method
    Patent number: 12038409
    Abstract: A tube inspection unit (10) includes an eddy current probe (14). The probe (14) has a plurality of inductors and a plurality of receivers. The receivers are magnetoresistances having a substantially linear functional zone. The inductors of the probe (14) are linked to a controller (26). The controller (26) is programmed to inject, into the inductors, a voltage with a sinusoidal component and a nonzero direct-current component, such that the receivers have a polarization center situated inside the substantially linear functional zone.
    Type: Grant
    Filed: February 6, 2018
    Date of Patent: July 16, 2024
    Assignee: FRAMATOME
    Inventors: Yann Kernin, Marc Piriou, Jean-Marc Decitre, Frédéric Nozais

  • Assembly and method for detecting and measuring the fouling rateof flow holes in a secondary circuit of a pressurized water nuclear reactor
    Patent number: 9360207
    Abstract: An assembly for detecting and measuring the fouling rate by deposits containing at least one ferromagnetic material, including a probe which can be continuously moved inside a tube and which has a body carrying on its outer surface at least one magnetized source for self-orientation of the body of the probe, at least three magnetic field emitters and at least three magnetic field detectors each positioned between two contiguous emitters.
